Hi,

I am using Infragistics ultragrid controls in vb.net, after assigning the datasource to the grid it displays all the value as expected.

using the code how to move to the next row in the grid.  Ex. if i am currently in 3 row after changing  the value in the current cell ( After cell update event - ) after tab  out event or after lost focus  i want to move to next row of the grid.

Regards,
Kiran.

My opinion is to don't use data binding in Controls.  Open a ADO.NET recordset instead and change the ultragrid with code instead.  In VB6 most Experts would agree, however in VB.NET I have read that this is in much debate.  I still program in VB6 and use DBi-Tech controls now,  Infragistics appear to be #1 in controls for .NET .  I was wondering if the code was alittle 'long winded' needed to program these controls.

Kiran,

Try the UltraGrid's PerformAction method.  For example, here's a KeyDown event handler that moves the focus to the cell below the current cell using PerformAction (My grid is named uwgColEditor).  Look for the lines appended with '<<<<<<< below.  I believe that ActiveRow may work too.


    ' ****************************************************************************************
    ' uwgColEditor_KeyDown
    ' ABSTRACT: KeyDown event handler.  This event is raised each time a key is pressed while
    '   a cell is active in the grid.  Here we are trapping the RETURN key.  When this
    '   key is pressed, the focus is moved to the next cell down in the grid.  This facilitates
    '   simplified editing since the user's hands don't have to leave the keyboard.
    '
    '   This routine does nothing for all other keys pressed in the grid.
    '
    ' ****************************************************************************************
    Private Sub uwgColEditor_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles uwgColEditor.KeyDown
        If Not c_cellBadCell Is Nothing Then
            e.Handled = True
            uwgColEditor.ActiveCell = c_cellBadCell
            uwgColEditor.PerformAction(Infragistics.Win.UltraWinGrid.UltraGridAction.EnterEditMode, False, False)
            c_cellBadCell = Nothing
        Else
            If Not ((uwgColEditor.CurrentState And UltraGridState.InEdit) = UltraGridState.InEdit) Then Exit Sub
            If e.KeyCode = Keys.Enter Then      'Enter Key pressed?
                uwgColEditor.PerformAction(UltraGridAction.ExitEditMode, False, False)     '<<<<<<<
                uwgColEditor.PerformAction(UltraGridAction.BelowCell, False, False)          '<<<<<<<
                uwgColEditor.PerformAction(UltraGridAction.EnterEditMode, False, False)  '<<<<<<<
                e.Handled = True
            End If
        End If

    End Sub
